Equine asthma is a chronic, non-infectious inflammatory disease of the lower airways in horses, classified as mild to moderate (MEA) or severe (SEA). Its pathogenesis is not fully understood and is influenced by environmental and seasonal factors. In this cross-sectional study, seasonal effects on the bronchoalveolar lavage fluid (BALF) metabolome were investigated in asthmatic and non-asthmatic horses. The metabolome of 230 BALF samples from horses across different seasons, classified as cytologically unremarkable (CUA), MEA, or SEA, was analyzed using proton nuclear magnetic resonance spectroscopy (1H-NMR). Principal component analysis was performed for each season, and metabolite profiles were statistically compared between seasons within each group. Altered metabolites were subjected to pathway enrichment analysis using the FELLA R package. Asthmatic horses showed significant seasonal changes in metabolite concentrations between warm and cold seasons, whereas only trends were observed in CUA horses. Pathway analysis indicated enrichment of cholesterol metabolism across all groups. The mTOR signaling pathway was only enriched in SEA horses. Several metabolites—including valine, taurine and carnitine —were altered during the transition from winter to spring in asthmatic horses. These findings indicate that the winter to spring transition significantly modulates the airway metabolome in asthmatic horses, particularly in SEA-affected animals.by Gift Treighcy Banda-Mtaula, Ibrahim Simiyu, Sangwani Nkhana Salimu, Stephen A.

Multimorbidity, the presence of multiple chronic health conditions, is a leading cause of death globally. In Malawi, chronic noncommunicable and communicable diseases such as HIV frequently co-exist, putting pressure on an under-resourced system. However, the health system is primarily structured around disease-specific [vertical] programs, which hinders person-centred care approaches to multimorbidity. Our study focuses on multimorbidity care and explores the perceptions of healthcare workers on the patient pathways and service organisation throughout the patient’s interaction with the health facilities. This cross-sectional qualitative study took an interpretivist approach. We conducted 13 days of clinical observations at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. We also conducted 13 days of clinical observations and semi-structured in-depth interviews with different cadres of purposively sampled healthcare workers (n = 22) at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. Through thematic analysis, we identified an understanding of the organisation of care and healthcare workers’ perspectives on the delivery of services. Findings showed both hospitals provided services for inpatients and outpatients with multimorbidity, including screening, management, prevention of secondary conditions and rehabilitation. Patient diagnosis and management for multimorbidity were often delayed due to frequent stockouts of medication and consumables necessary for diagnostic testing for NCDs at the hospital level. Some healthcare workers were not equipped with the knowledge, skills, or guidelines to manage multimorbidity. As HIV care is currently better resourced than other chronic conditions, healthcare facilities may strengthen the supply chain, healthcare workers’ training sessions and monitoring and evaluation tools to ensure NCDs are well managed, learning from HIV programmes.This multi-centre, randomised controlled trial (RCT) investigates the effects of intensive upper limb (UL) motor training on neurophysiological and functional recovery in individuals with cervical spinal cord injury (c-SCI) during the sub-acute phase. The study aims first to assess neurophysiological adaptations in the central and peripheral nervous systems and functional changes to evaluate the impact of intensive UL motor training on recovery. Second, it determines dose dimensions and their correlation with neural and functional improvements.
A total of 44 individuals with c-SCI within 13 weeks post-injury will be recruited from five rehabilitation centres in Belgium and the Netherlands. They will be randomised into an intervention group, receiving six additional hours of goal-directed UL training per week for 8 weeks, or a control group receiving standard care. Primary outcomes are changes in resting motor threshold, a proxy for corticospinal tract integrity; compound muscle action potential amplitude, indicating peripheral nerve excitability and functionality; and assessments of strength, sensory function and prehension, with the primary comparison between groups at baseline and after the intervention period. Secondary outcomes cover additional neurophysiological assessments and motor function. Dose dimensions will be quantified and related to primary and secondary outcomes.
The central medical ethics committees, METC Máxima MC (NL84212.015.23) and MEC Gent (B6702023000227), as well as local ethics committees, reviewed and approved this trial. The protocol is registered (ClinicalTrials.gov; NCT06065384). The findings of this RCT will be disseminated through articles in peer-reviewed journals and at neurological rehabilitation conferences.
Alcohol use disorder and treatment-resistant depression (TRD) often co-occur, presenting a major clinical challenge with limited effective treatments. However, ketamine produces rapid antidepressant effects and has shown promise in reducing alcohol use, and acceptance and commitment therapy (ACT) can be effective for both substance use and mood disorders. This study explores the feasibility and acceptability of combining ACT with ketamine within the framework of the Montreal Model—a structured, integrative psychedelic ketamine therapy developed for severe TRD.
This study is a single-group, open-label feasibility trial at the Centre hospitalier de l'Université de Montréal (CHUM) Neuromodulation Ketamine Clinic in Montreal, Canada. 30 participants diagnosed with both alcohol use disorder and treatment-resistant depression will receive eight weekly in-person or virtual ACT sessions in addition to six intravenous ketamine infusions. The primary outcome is feasibility, assessed through study completion and protocol adherence. Secondary outcomes include recruitment rate, tolerability, safety, data completeness and healthcare resource use. Exploratory measures will examine changes in depressive symptoms, alcohol use and quality of life using validated tools. A subset of participants will participate in semistructured qualitative interviews to explore their experiences.
This study was approved by the ethics committee of the CHUM on 14 May 2025. The results of the trial, including primary and secondary outcomes, will be published in peer-reviewed scientific journals.
Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting up to 14% of the French children. Topical treatments are restrictive, leading patients to seek alternative options. Medical hypnosis may be a therapeutic approach, providing hypno-analgesia through comfort and soothing of the skin as well as anxiolysis by managing stress and boosting self-esteem. To date, only five studies have explored medical hypnosis in AD, showing promising results but limited by small sample sizes and lack of control arms. This study protocol describes the methodology for an initial evaluation of medical hypnosis within a therapeutic patient education (TPE) programme, called Hypno-DA.
The Hypno-Atopic Dermatitis (Hypno-AD) study is a prospective, monocentric, non-blinded, parallel, cluster-randomised controlled trial conducted at the University Hospital of La Reunion, France. The study commenced on 13 August 2024 and is scheduled to conclude on 13 August 2026. The primary objective is to assess the feasibility of recruiting for a medical hypnosis programme for children with mild-to-severe AD. 32 patients (aged 8–17 years) will be randomly allocated in a 1:1 ratio to receive TPE sessions combined with medical hypnosis (experimental arm) or the usual TPE sessions performed for AD without medical hypnosis (control arm). The experimental arm will employ a hypnosis-based intervention, referred to as the ‘superhero costume’ technique. Reinforcement will be provided through the practice of self-hypnosis at home, guided by listening to an audio recording provided on a Universal Serial Bus (USB) key. Secondary outcomes will be assessed at 1-month, 3-month and 6-month post-randomisation. These will include compliance with the required practice of self-hypnosis at home, rate of loss of follow-ups, patient satisfaction, effectiveness of the hypnosis programme on the control of AD (ADCT) and severity of AD (Patient-Oriented SCORing Atopic Dermatitis) and the global impression parents may have concerning the changes in their child’s AD.
Ethics approval was obtained from the Ile de France I Research and Institutional Ethics Committee (No. 2022-A01153-40). All methods were carried out in accordance with French law No. 2012-300 (5 March 2012) related to research involving humans as well as Good Clinical Practices (International Council for Harmonisation (ICH) version 4 of 9 November 2016, and the decision of 24 November 2006). Methods will conform to the Declaration of Helsinki. Informed oral consent from at least one legal guardian of each participant will be obtained in addition to oral consent from the child. Results will be published in an indexed peer-reviewed journal as well as presented and disseminated at scientific conferences.
To determine the predictors of pressure injuries among residents living in Sri Lankan nursing homes.
A prospective multi-site longitudinal cohort study design.
Semi-structured observations and chart audits were used to gather data on 17 predictors of pressure injury from a consecutive sample of 210 residents (aged ≥ 60 years old) from nine nursing homes in Sri Lanka. Data were collected at baseline and followed up every week until the study endpoint: a new pressure injury or reaching the maximum 12 weeks of data collection, from July to October 2023. Validated semi-structured data collection forms and chart audits were utilised. Binary logistic regression was used to identify the predictors of pressure injuries. Generalised linear mixed models were used to assess the association between predictors and the development of new pressure injuries.
The cumulative incidence of pressure injuries was 17.1% (36/210) during the 12 weeks. The number of medical devices and baseline pressure injuries predicted the development of new pressure injuries. Each additional medical device increased the likelihood of developing a pressure injury by 2.3-fold, and individuals with a baseline pressure injury were 2.1 times more likely to develop a new pressure injury.
Multiple medical devices and baseline pressure injuries are predictors of pressure injury in older residents living in nursing homes.
This study provides evidence of pressure injury predictors among older residents living in nursing homes. Early identification of high-risk residents with an existing pressure injury and those with multiple medical devices is important for nurses and managers at nursing homes. Accurately assessing residents' risk of a pressure injury may result in implementing various preventive strategies that may ultimately help prevent future pressure injuries.

Identify desired training content for shift-working nurses to improve their sleep and fatigue.
A descriptive qualitative design.
We recruited night shift nurses (N = 23) to provide feedback during virtual focus groups/interviews. Data collection occurred in the U.S. between March and June 2024. Participants were presented with sleep and fatigue topics derived from the literature. Focus group/interview data were collected and transcribed. Data were analysed using a hybrid deductive-inductive manifest content analysis with an a priori coding schema based on topics shared during data collection. Data not fitting the schema, yet informing content, were analysed inductively.
Three themes aligned with literature-derived topics. Theme 1, Why We Sleep and Why Should Nurses Care, explains the importance of sleep to health. Theme 2, Sleep Practices for Nurses to Support Health and Social Relationships, describes healthy strategies to promote sleep for enhanced quality of life. Theme 3, Fatigue and Work, illustrates the significance of nurse sleep and fatigue risk mitigation to safe working conditions and patient care.
Study findings highlight night shift nurses' interest in gaining evidence-based information to promote their sleep. Sleep education and training could fill a knowledge and skills gap, not often offered in school or workplace.
Identifying themes relevant to nurses may help increase the development and availability of sleep education and training currently tailored for nurses.
Study findings describe content night shift nurses' desire for sleep and fatigue training, serving as an important first step in developing programmes most relevant to shift-working nurses. Our analysis found the findings largely align with key components workers should receive in sleep education and training and reinforced the need for employers to offer such training. This study could benefit the nursing workforce and employers who expect rested, high-functioning nurses to care for patients.

To synthesise the evidence on implementation strategies used to implement transitional care interventions for adult surgical patients.
Scoping review.
Medline, CINAHL and EMBASE were searched in August 2023 and updated June 2025, followed by citation searches. Studies were screened independently by two researchers, and one extracted data, another verified its accuracy. Studies about transitional care interventions for adult surgical patients were coded according to the ‘Five classes of implementation strategies’ and the ‘Patterns, Advances, Gaps, Evidence for practice and Research recommendations’ framework, to illuminate the review findings.
Based on 27 studies included in the scoping review, staff education, changes to staffing and electronic systems, and change management techniques were frequently used implementation strategies. Implementation strategies were mostly used with patients undergoing colorectal and cardiac surgery in Asia and the United States. Scale-up strategies and capacity-building initiatives for people in charge of spearheading the change initiatives were less common.
To further the field, future research could focus on capacity-building and scale-up strategies, fidelity reporting, and financial implications of implementation in a wider range of surgical populations and settings. Work is needed to effectively implement surgical transitional care interventions in real-world settings.
Our findings provide strategies for hospital leaders to adopt when implementing transitional care interventions for surgical patients.

Primary biliary cholangitis (PBC) is a rare chronic cholestatic disease that despite current therapy has significant ongoing unmet needs, including risks of cirrhosis and life-impairing symptoms. The current treatment approach is a step-up model, wherein first-line therapy, ursodeoxycholic acid (UDCA), is given for a minimum of 12 months before the addition of second-line therapy is considered for non-responding patients. This ‘waiting to fail’ approach, focused on the needs of low-risk patients, allows, we postulate, a key process of biliary epithelial cell (BEC) senescence to become established, driving accelerated bile duct loss and aggressive disease. Preclinical mouse modelling has shown that early use of the farnesoid X receptor agonist obeticholic acid (OCA), currently only used as second-line therapy following UDCA failure, reverses BEC senescence, changing the clinical course of disease. Here, we describe the design of the Optimising Primary thErapy in pRimAry biliary cholangitis (OPERA) trial. The aim of OPERA is to explore a new paradigm for disease-modifying treatment of PBC: risk-informed early treatment stratification, with patients at increased risk offered UDCA and OCA combination with the goal of complete biochemical remission.
OPERA is a multicentre, randomised, double-blind, placebo-controlled trial of OCA in combination with UDCA, as first-line treatment for high-risk PBC. This is a multicentre trial in England, which will be undertaken in specialist clinics in secondary/tertiary referral centres (or as per local set up). These centres will be specialists in the area of PBC management and will manage patients from across their local region. OPERA will recruit and randomise 106 adults, within 6 months of PBC diagnosis, who are at an enhanced risk of non-response to standard first-line therapy, between either: (1) UDCA and OCA or (2) UDCA and matched placebo in a 1:1 ratio. The primary efficacy outcome measure is the percentage of participants showing normalisation of serum alkaline phosphatase and total bilirubin values at 26 weeks (disease remission).
Favourable ethical opinion was received from London – Riverside Research Ethics Committee (reference: 22/LO/0878). Potential participants will be fully informed of their rights and the benefits and harms of the trial by the research team before giving informed consent to participate in the trial. Results will be disseminated in peer-reviewed publications, at national and international conferences, in peer-reviewed journals and to participants and the public (using lay language).

Reprogramming of energy metabolism is one of the hallmarks of cancer cells and mutations that modify wild type intestinal cells to colon carcinomas increases cellular energy expenditure. Mitochondria are the main site for ATP production in (cancer) cells and disrupting their function results in impaired tumor forming efficacy. The mitochondrial ribosomal proteins (MRPs) constitute the ribosome specifically in mitochondria, and as such are crucial for the translation process of the electron transport chain complex subunits. We hence aimed to explore the consequence of reduced MRP expression on adenomagensis and investigate this in a genetic mouse model with bodywide heterozygosity for Mrpl54. We show that Mrpl54 heterozygosity does not alter adenoma formation, intestinal proliferation or apoptosis in a heterozygous Apc model. Furthermore, diminished Mrpl54 expression did not decrease stemness or global parameters of metabolism in colorectal cancer cell lines.A qualitative study was conducted in Catalonia (Spain), incorporating the views and opinions of relatives, healthcare professionals and patients on what they considered a ‘good death’. This study aimed to describe barriers, facilitators and unmet needs related to the achievement of a good death.
We recruited adult patients with advanced or chronic conditions, relatives and health and social care professionals involved in end-of-life processes of care, management or strategic planning. All participants took part in a qualitative study. The study was informed by phenomenological, hermeneutical and social constructivist perspectives and included 23 in-depth interviews and three focus group discussions with a total of 31 participants. Fieldwork was conducted between February and April 2022. Data were transcribed and analysed using qualitative thematic content and discourse analysis.
Six main themes were identified, comprising 17 subthemes. Facilitators and barriers related to achieving ‘a good death’ were categorised according to whether they occurred before death or during the dying process. Key facilitators include high-quality palliative care, open communication about death and the ability to choose the place of death. Key barriers included bureaucratic delays, inadequate resources, insufficient professional training and lack of respect for patients’ preferences and wishes.
Our study highlights the need to understand factors that facilitate or hinder the achievement of a good death and the quality of the dying process. Specifically, understanding individual preferences and unmet needs, enhancing communication, increasing awareness, reducing bureaucratic barriers and ensuring adequate resources are essential to support a more dignified end-of-life experience for patients, caregivers and healthcare professionals.
A significant proportion of infants born at ≤29+6 weeks’ gestation develop lung disease during the neonatal period, thus putting them at risk of developing prematurity-associated lung disease in childhood and adulthood. After discharge from the neonatal unit, pre-existing lung disease in preterm-born infants is exacerbated by (often frequent) respiratory viral infections requiring greater health utilisation, including hospital admissions, than their term-born equivalents. Opportunities to prevent viral infections in infancy are largely limited to anti-respiratory syncytial virus (RSV) antibody prophylaxis and recently maternal RSV immunisation, but in term-born infants, trained immunity-based vaccines such as Bactek (MV130, Inmunotek, Spain) are increasingly used. Bactek provides a promising therapeutic avenue for preterm-born infants to target postdischarge respiratory viral infection in this vulnerable group of infants. The BALLOON study aims to assess this treatment in a very/extremely preterm-born population and determine if treatment with the trained immunity-based vaccine Bactek decreases the risk of unscheduled visits to healthcare professionals for lower respiratory tract infections, when compared with placebo. Included infants are born at ≤29+6 weeks’ gestation and treated daily from term-equivalent (37–43 weeks’ postmenstrual age, PMA) or from discharge, if earlier, up to 1 year of corrected age.
542 infants are being recruited prior to discharge by neonatal units in the UK. They are being randomised to receive Bactek or placebo, once daily dose of 2 sprays (each 0.1 mL) of IMP (300 Formazin Turbidity Units), from 37 to 43 weeks’ PMA or discharge if earlier up to 1 year of corrected age. The primary objective is to assess if sublingual Bactek spray decreases the risk of health professional diagnosed lower respiratory tract infections (LRTIs) (unscheduled visits to general practitioners, accident and emergency departments and hospital admissions) between enrolment and 1 year of corrected age. Secondary outcomes include the number of parent-reported, health professional-confirmed unscheduled visits for LRTIs, the time to first parent-reported, health professional-confirmed unscheduled visit for LRTI, parent-reported wheeze episodes (identification aided by WheezeScan (Omron, Japan)), parent-reported use of respiratory medications, growth (weight, length and head circumference), parent(s)/guardian(s) reported time missed from work and/or nursery time missed for the infant and volume of adverse reactions. Viruses associated with LRTIs will also be identified.

To map the current literature on the characteristics of nurse-related medication errors in perioperative healthcare settings.
A scoping review.
This scoping review used the five-stage framework developed by Arksey and O'Malley (2005). The five stages are: (1) Identifying the Research Question; (2) Identifying Relevant Studies; (3) Study Selection; (4) Charting the Data; and (5) Collating, Summarising, and Reporting the Results. Findings were synthesised using the PAGER framework. An Ishikawa diagram was used to illustrate contributing factors of nurse-related medication errors.
In October 2024, using key search terms, five databases (Scopus, EBSCO Cumulative Index to Nursing and Allied Health Literature, OVID Embase, EBSCO Medline, EBSCO PsycInfo) and two grey literature platforms (opengrey, Policy commons) were searched. The articles were imported to the Covidence database from Endnote after removing duplicate literature. Selected article titles and abstracts, and subsequently full-text articles, were screened by two trained reviewers based on a priori inclusion and exclusion criteria. Data were extracted from the included full-text articles by one author, checked by another, and analysed descriptively.
Of the 967 articles identified through the searches, 7 full-text articles were included. The incidence of nurse-related medication errors in perioperative settings ranged from 6.4% to 33.7%, with errors including incorrect medication routes, missed or delayed doses, and miscommunication-related overdoses. Contributing factors were multifaceted, involving workload pressures, communication failures, system flaws, and organisational influences such as leadership and safety culture.
Medication errors in the perioperative setting pose a significant threat to patient safety yet remain underexplored compared to other healthcare contexts. A holistic approach incorporating human factors frameworks, improved communication, workload management, and leadership can help address the complex causes of these errors and guide targeted interventions to enhance perioperative safety and patient outcomes.

Overmedication of off-label use of psychotropic medicines to address behaviours of concern in people with intellectual and developmental disabilities is a major public health concern. Disability support workers (DSWs) play a pivotal role in supporting adults with intellectual and developmental disabilities who are prescribed psychotropic medicines. Therefore, there is an urgent need to train DSWs to help understand the appropriate use of these medicines. This paper describes the protocol of a project that aims to develop such a programme.
A participatory action framework will underscore the programme and follow a Universal Design for Learning approach. It will be a co-production involving all stakeholders, including people with intellectual and developmental disabilities, their families, members of the disability workforce, healthcare professionals and educational designers. The programme will be developed using the following steps: (a) development of a consumer advisory committee and expert panel groups, (b) an online survey of learning needs analysis, (c) a rapid umbrella review of the relevant literature, (d) focus groups involving participants from different parts of Australia, (e) co-design events in four Australian cities, (f) field testing on 6–12 DSWs to determine any practical difficulties of implementing the programme, (g) a feasibility trial involving at least 1200 DSWs using a train-the-trainer model and online resources and (h) a mixed-method process evaluation using interviews of a purposive sample of trainees and online questionnaire survey.
Ethics approval will be sought at each stage of the co-design process. Each step of the project will include an academic language paper and Easy Read report developed. The training programme will be shared across Australia, with DSWs able to complete the project for free. We expect the training will help improve DSWs’ knowledge of appropriate psychotropic medicine prescribing in people with intellectual and developmental disabilities, confidence in effectively communicating with health professionals and using non-pharmacological approaches to support behaviours of concern, promote shared decision-making with clients, advocate for psychotropic medicine reviews by healthcare professionals, encourage positive interactions with people with intellectual and developmental disabilities and their families and self-reflection on their own behaviour and attitude can influence their client and behaviours of concern.

AimsTo characterise symptoms, function and patient-reported outcome measures (PROMs), and identify associated factors in adults with persisting respiratory symptoms post-COVID.
MethodsCross-sectional analysis of 210 non-hospitalised adults referred to a post-COVID respiratory clinic (December 2020-July 2024) who consented to research. Assessments included demographics, symptoms, lung function, chest CT, and several PROMs: MRC dyspnoea score, Nijmegen Questionnaire score (NQ), Hospital Anxiety and Depression Scale, Chalder Fatigue Scale, Short Physical Performance Battery (SPPB) and Fried Frailty Index. Multivariate logistic regression examined key exposure-outcome associations.
ResultsAmong participants (mean age 49.4 years; 68% female; median 13.3 months since COVID-19 diagnosis), 95% reported shortness of breath, 54% had clinically significant breathlessness (MRC ≥ 3), 68% had an NQ score (>23) consistent with dysregulated breathing, 32% had a low SPPB score ( Conclusion
In non-hospitalised patients with persistent respiratory symptoms post-COVID, dysregulated breathing, deconditioning and psychological distress were key factors linked with symptom burden. These findings suggest a multidisciplinary approach should be considered to optimise recovery.

The microsporidium Vairimorpha (Nosema) ceranae is an emerging threat to honey bees (Apis mellifera), known to disrupt gut microbiota and suppress immune responses, potentially contributing to colony losses. Fungal extracts have recently gained interest as sources of bioactive compounds with antimicrobial and immunomodulatory potential. In this study, we explored the effects of different dietary supplements—sugar syrup, HiveAlive™, and a novel Ganoderma australe extract (GanoBee)—on gut bacterial composition and immune-related gene expression in honey bees subjected to experimental exposure to V. ceranae 1 x 104 spores per bee. The GanoBee diet altered the gut microbiota, notably reducing the relative abundance of Rhizobiaceae (Bartonella apis) and increasing Frischella compared to other treatments. While alpha diversity was not significantly affected by diet or exposure to V. ceranae, beta diversity differed significantly in bees fed with GanoBee. Additionally, the expression of the antimicrobial peptide genes abaecin and hymenoptaecin was elevated in both exposed and unexposed bees fed with GanoBee, depending on the sampling day. However, the establishment of V. ceranae infection appeared limited, likely due to low spore viability, and mortality in control bees was higher than expected. The low Vairimorpha ceranae infection levels observed in this study are likely attributable to reduced spore viability caused by storage conditions and/or suboptimal environmental conditions within the laboratory cages. Post hoc analyses indicated that the high viscosity of GanoBee-supplemented diets likely contributed to the elevated bee mortality observed, underscoring a critical limitation of the experimental design related to diet formulation and delivery method. These physical factors complicate the interpretation of treatment efficacy and highlight the importance of optimizing feeding protocols to avoid confounding effects. Despite these constraints, GanoBee demonstrated promising potential as a modulator of gut microbiota composition and immune-related gene expression, supporting the need for further research under improved and carefully controlled experimental conditions.Necrotising soft tissue infection (NSTI) is a progressive disease with a time-dependent prognosis; if not promptly treated, it can lead to significant morbidity as well as mortality. Early and aggressive surgical treatment is mandatory for appropriate management. This study reports the diagnostic and therapeutic pathway, surgical treatment and outcomes in a single-centre series. Data from 40 patients with NSTI treated between 2015 and 2024 were retrospectively analysed for demographic and social information, microbiological results, therapeutic course, clinical outcome and mortality. TC Indication and timing, the role of limb amputation in critical patient survival and reconstruction technique were also reviewed. Fourteen patients (35%) were referred at an advanced stage due to avoidable delay. The mean number of surgical interventions for a single patient was 4. Eight patients (20%) underwent limb amputation. Skin grafts were the most used reconstruction procedure. Seven patients (17.5%) died in the hospitalisation. NSTI is a life-threatening disease requiring prompt diagnosis and treatment within dedicated clinical pathways. Our series highlights the fundamental role of TC in critical patients or unclear diagnosis, and limb amputation as a life-saving procedure even at admission in severe cases.
Black women in early midlife experience disproportionate exposure to stress and elevated cardiovascular risk, including hypertension. Despite this, few stress management interventions are designed with and for this population. This study aims to explore the lived experiences of stress and coping among black women in early midlife with elevated blood pressure to inform the codesign of a culturally relevant, multilevel stress management intervention.
We will conduct one-time, semistructured focus groups with black women aged 35–50 who have elevated blood pressure, recruited from a large safety-net health system. Data will be analysed using a constructivist grounded theory approach, with inductive theme development supported by line-by-line, focused and theoretical coding. The Social Determinants of Cardiovascular Disease framework will serve as a sensitising guide to multilevel contextual factors rather than a prescriptive coding structure. An artificial intelligence (AI)-assisted analytic component will complement human-led analysis by supporting preliminary theme exploration and enhancing transparency.
Approved by the Indiana University Institutional Review Board (Protocol #21785). All participants will provide written informed consent. Findings will be shared via peer-reviewed publications, conference presentations and lay summaries for stakeholders.
